Application filed F br ar 11, 1897. Serial No. 622,915. (No model.)

To all whom it may concern:

Be it known that we, FRANK E. STANLEY and FREELAN O. STANLEY, of Newton,county of Middlesex, State of Massachusetts, have invented anImprovement in Gas-Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters and figures on the drawings representing like parts.

This invention has for its object to improve the construction ofgas-machines wherein naphtha or some other equivalent hydrocarbon liquidis converted into a gas for illuminat in g and other purposes, such agas being commonly known as air-gas.

In accordance with this invention an airpressure device is employed fordelivering air to the carbureter, and a delivering device is employedfor delivering hydrocarbon liquid to said carbureter, and means areprovided for operating said air-pressure and liquid-delivering devicesconjunctively to store up a supply of air and hydrocarbon liquid, andsaid devices also operate conjunctively. to simnltaneously deliver thestored-up air and liquid in uniform proportions to the carburotor.

The quantities of airand hydrocarbon liquid stored up at eachconjunctive operation of the air-pressure and liquid-delivering devicesare proportionate to the quantities required in producing a certainquantity of gas of the desired quality, and as said devices operate conj unctively they will also deliver their respective stored-up suppliesto the carbureter in uniform proportions.

The action of the delivering device is made absolutely dependent uponthe action of the air-pressure device, and to accomplish this result thedelivering device is constructed and arranged to be operated directly bythe airpressure device instead of by the motive power or means which isemployed to operate said air-pressure device, and, as herein shown, thesaid delivering device is operated directly by the air-pressure deviceto first store up a measured quantity of hydrocarbon liquid and isthereafter operated by said air-pressure device to deliver its stored-upsupply to the carbureter. Our invention, however, is intended to includethe important feature of operating the delivering device directly by theair-pressure device and utilizing the motive power solely for operatingthe air-pressure device, even in case a supply of hydrocarbon liquidshould not be stored up at each operation.

The air-pressure device comprises, essentially, a gravitatingair-receiver, and means are provided for raising it to store up a meas-6o ured quantity of air which will be subsequently delivered to thecarburetor, and said gravitating air-receiver is herein shown asconnected with the operating member of the delivering device, so that assaid air-receiver is raised to store up a quantity of air the deliveringdevice will be operated at the same time to store up a proportionatequantity of hydrocarbon liquid, and as said air-receiver falls bygravity to deliver its stored-up sup- 7o ply of air to the carbureterthe delivering device Will be operated at the same time to deliver itsstored-up supply of hydrocarbon liquid to the carbureter, the action ofthe delivering device being thus absolutely depend- 7 5 cut upon theaction of the air-pressure device.

As herein shown, the hydrocarbon liquid is expelled from the deliveringdevice by displacement that is to say, the delivering device may consistof a receptacle which contains a supply of hydrocarbon liquid, and abody--such, for instance, as a hollow vessel, tube, or rodis adapted tobe moved up and down in said receptacle and when descending to expel thehydrocarbon liquid by displacement.

As a means of supplying the delivering device with hydrocarbon liquid asupply-tank is provided, Which maybe located at any suitable orconvenient place and which will contain a large supply of hydrocarbonliquid, and as herein shown a stand-pipe rises from said supply-pipewhich is connected with said delivering device, a valve being employedto control the passage from said stand-pipe to 5 said delivering device.The hydrocarbon liquid is maintained in said stand-pipe at apredetermined elevation, so that whenever the controlling-valve isopened a measured quantity will flow from the stand-pipe into thedelivering device to be subsequently (lelivered to the carburetor. Theliquid is caused to rise in said stand-pipe by means controlled andoperated automatically in order that the stand-pipe will be filled atall times sulliciently to supply the delivering device with a measuredor predetermined quantity.

Many of the parts herein to be described are novel and are included inthis invention, as well as connections whereby certain con- ;i unctiveand automatic actions are produced, as will be hereinafter more fullyspecified.

Figure 1 shows in side elevation a gas-machine embodying this invention;Fig. 2, a side elevation of the actuating device for the air-pressuredevice; Fig. 3, a detail of the means employed for maintaininghydrocarbon liquid in the stand -pipe at a certain level; Fig. 4:, adetail to be referred to; Fig. 5, a side elevation of a portion of thegas-machine shown in Fig. 1; Fig. 6, a vertical section of thedelivering device by which the hydrocarbon liquid is delivered to thecarbureter; Fig. 7, a detail showing the indicator by which theoperation of the machine may be observed; and Fig. 8, a vertical sectionof the valve which forms the essential element of the actuating device,which is solely connected with and adapted to operate the airpressuredevice.

The air is supplied or delivered to a carbureter or converter 0 by meansof an air-pressure device, which consists of a tank or hollow cylindera, nearly filled with water and open at the top, and a hollowair-receiving cylinder 1), open at the bottom only and made smaller indiameter than the cylinder at and suitably suspended or supported abovesaid cylinder at and adapted to rise and fall within said cylinder a,thus working substantially on the principle of an ordinary gasometen;

It is designed and intended that the operation of said air-pressuredevice to store up and to deliver air to the carbureter shall be carriedon without attention or action on the part of the user, and also thatthe actuating device jecting upwardly from its closed top wall, and

said rod 1) has attached to or mounted upon its upper end a plunger orpiston a, which is adapted to fit tightly and work up and down within acylinder D which may be held in an upright or vertical position by asuitable frame or support L to which it is attached. A pipe '0' leadsfrom the valve u to said cylinder b entering it at a point below thepiston a, and the water is forced through the pipe The air-receivingcylinder or air-receiver Z2 has a rod 1) fixed to and pro 01' into saidcylinder b moving the piston or plunger a upward, and thereby bodily1ift ing the air-receiver b. As the air-receiver Z) is thus raised theair is admitted and stored up for subsequent delivery to the carbureteras said receiver Z2 falls by gravity. Thus the air-pressure device isoperated to store up air by water admitted under pressure, and operatesto expel or deliver said air by the falling of its gravitatingair-receiver b. The valve 1), Fig. 8, which controls the admission ofwater under pressure to said cylinder 17*, c011- sists of two cylinderso '0 located side by side and connected by a short pipe W. The cylinder'1) has a chamber 41 within it, provided with an inlet-port 'v for theinlet of the water, and an inlet-pipe o is connected with said cylinder41 at such point. At the bottom of said chamber 4: a valve-seat o islocated, which when open allows the water entering the chamber c to passthrough it into the chamber 219 below said valve-seat and then into thepipe 1). A valve 12 is contained in the chamber 0 which is attached to arod i2 passing'out through the upper end of the cylinder c and saidvalve is adapted to close on said valve-seat o to shut off the supply ofwater, preventing the water from entering the pipe 7). It will be seenthat when said valve 11 is raised, as shown in Fig. 8, the water is freeto enter the chamber and flow into the pipe 41, and when said valve isseated the water is shut off. The cylinder t has a chamber 12 within itand has also a valve-seat i1 and a valve 12 is adapted to close on saidseat which is attached to a rod c", which passes out through the upperend of the cylinder c Above the valve-seat v another chamber 41 isprovided, having an outletport r ",to which an outletpipe c isconnected. The short pipe 11 connecting the two cylinders '0 is in opencommunication with the chambers 229 and 12 The two valve-rods r and rare connected together by a cross-head 01 so that the two valves will besimultaneonsly operated. It will be seen that as the valve c is raised,and thereby removed from its seat, the valve o will be closed on itsseat, and with the parts in such position, as shown in Fig. 8, the wateris free to enter and flow into the pipe '0 for the purpose of raisingthe air-receiver b, and as soon as said valves are operated in theopposite way, the valve n closing upon its seat and the valve 11 leavingits.seat, the supply of water will be shut off and an open passageprovided from the pipe 4; through the chamber u", pipe 21 chambers r ando, and through the outlet-port v to the outlet-pipe c. The crosshead 11of the valve 11, which controls the admission of water under pressure tosaid cylinder W, is connected to a plate 1), (see Fig. 2,) which ispivoted at m to the frame and as said plate is turned on its pivot inone or the other direction the valve 4) will be opened and closed. Toturn said plate rom its pivot in one or the other direction to therebycon- ITO trol the action of the valve o, and thus control the admissionof water, the arm m is pivoted at m and provided at its outer end with aweight w, and said arm is adapted to occupy two different positions,one, as shown in full lines, Fig. 2, wherein said arm rests upon a pin19, projecting laterally from the plate 19, and the other, as shown bydotted lines, wherein said arm rests upon the pin m projecting laterallyfrom said plate 19, and as the pivot m is between said pins it will beseen that the plate will be turned in one or the other direction by theto-and-fro movement of the arm m. l/Vhen the arm m is in the full-lineposition shown, resting upon the pin p,the plate 19 is turned to closethe valve 0), and when said arm is moved into the dottedline positionshown said plate 10 will be turned to open said valve Q). Toautomatically control the valve '0 by means of the airpressure device ab, we provide mechanism whereby said actuating-arm m Will be operated bythe rising-and-falling air-receiver b. An arm m is provided foroperating the arm m, it being pivoted at m in front of the plate 19, andthe arm m has a pin m projecting from itlaterally at a point near itspivot m against which the lower end m of said arm m bears when said armm is in the full-line position shown in Fig. 2. As said arm m isdepressed or caused to occupy the dotted-line position shown, its lowerend m by engaging the pin on" will positively raise said arm m to avertical position and cause it to pass the center, when said arm on willfall by gravity into its dotted-line position, and as said arm m israised or caused to occupy its fullline position it will engage said pinm on the arm m, but at the opposite side of its pivot, and will movesaid arm m into a vertical position and cause it to pass the center,when it will fall by gravity into the full-line position shown. Thus bydepressing said arm m the arm m will be caused to move from its full toits dotted line position and in so doing will rock the plate 1) and openthe valve 7:, and by raising said arm the arm m will be caused to returnto its full-line position, and in so doing will return the plate 1) andclose the valve o. To thus depress and elevate the arm m to operate thearm m, it is made long enough to enter and work between or cooperatewith two nuts m m, adj ustably located upon and at the upper part of therod m which is fixed to and projects upwardly from the top wall of thegravitatin g air-receiver b, and as said airreceiver falls the uppermostnut on will engage said arm m and depress it a certain distance,sufficient to raise the arm m and cause it to pass its center in orderthat it may fall into the dotted-line'position shown by gravity, andwhen said arm m thus falls its pin m will strike the arm m at theopposite side of its pivot and will further depress said arm m and assaid air-receiver rises the lowermost nut in will engage said arm m andelevate ita certain distance, sufficient to raise the arm m from itsdotted-line position into a vertical position and cause it to pass thecenter in order that it may fall into the full-line position shown bygravity, and when said arm m thus falls its pin hi will strike the arm mat the opposite side of its pivot and further elevate said arm on,causing it to bear against the uppermost nut m Thus it will be seen thatwhen the valve is open the water under pressure will be admitted toelevate the air-receiver b of the air-pressure device and that when saidair-receiver h rises to a certain elevation the said valve 1* will beclosed and will remain closed while said air-receiver falls to expel theair and deliver it to the carbureter,and when the falling air-receiverreaches a certain point it will operate to open said valve 1; to againadmit the water. It will thus be seen that the air-pressure device isautomatically actuated to store up air to be thereafter delivered to thecarbureter and that its actuator is in turn controlled by theair-receiver b of said air-pressure device.

The valve 72, through which air is admitted to the air-pressure device,consists of an airtight box n, partly filled with a liquid, a pipe M,which passes down through the top wall of said box and extends down intothe liquid and terminates some distance below its level, and a pipe at,which leads from the top wall of said box n. The pipe n extends to andconnects with a T-coupling 30, located beneath the tank a, and a pipe 31extends from said T-coupling 30 up through the bottom of said tank a andthrough the liquid contained therein and terminates at a point above thelevel of said liquid. A check-valve of any wellknown or suitableconstruction (not shown) will be contained in the pipe 11 to preventback pressure of the air. As the airreceiver 7) rises a partial vacuumis produced within it, and air is drawn in through the pipe n andthrough the liquid in the box '17., and thence through the pipe 07/,T-coupling 30, and pipe 31 into the air-receiver b to equalize thepressure. This particular construction of valve for controlling theadmission of air is employed for the reason that it is air-tight. A piped leads from the T-coupling 30 to a short vertical pipe (1 which risesto a height just above the carbureter O, and a short horizontal pipe dis connected to the upper end of said vertical pipe (Z and to theopposite end of said short horizontal pipe (1 a vertical pipe (1 isconnected, which passes down along the side of the carbureter G to avalve (1 at or near the lower end of said carbureter O, and from saidvalve (1 a pipe connects with the lower end of the carbureter, and asthe air receiver Z1 falls the air contained therein is forced throughthe pipe 31, T-coupling 30, pipes (Z d d (Z and valve d and thence tothe carbureter O to mix with the hydrocarbon liquid which is beingsupplied.

A valve d" is placed in the pipe (1* or at some other convenient pointto permit passage of the air from the falling air-receiver b to the IIOcarbureter, but which closes when the pressure is removed-as, forinstance, while the air-receiver Z) is being drawn up by the action ofthe water admitted under pressure, and during which time the air isbeing drawn into said cylinder through the inlet-valve.

The hydrocarbon liquid to be consumed is contained in a supply-tank P,which may be located at any convenient or suitable place, and saidhydrocarbon liquid is delivered in its liquid state to the carbureter O,entering at the top thereof and being converted into gas as it passesdownward, and to accomplish this result a delivering, device of novelconstruction is employed, which is operated by and consequentlyconjunctively with the airpressure device, so that a proper delivery isinsured of both liquid and air in uniform proportions, yet the deliveryof the liquid is absolutely dependent upon the operation of theair-pressure device, and this conjunctive action of the deliveringdevice and airpressure device and the dependence of the action of theformer on the latter constitutes one of the most important features ofthis invention. The said delivering device (see Fig. 3) consists of along tube or cylinderf, which is secured in a vertical position to anupright 12 on the frame If 'and said tube or cylinder contains thehydrocarbon liquid which is to be delivered to the carbureter, and saidtubef is closed at both ends, except as hereinafter described, tothereby form a liquid holding receptacle. f represents a short tube orcylinder which loosely fits and is adapted to work up and down withinsaid long tube or cylinder f, it acting by displacement as it falls tocause the hydrocarbon liquidto rise in the cylinder, and to thus expelit, The tube f is attached to and suspended from a vertical rod f whichpasses up through a hole in the top of the cylinder, and the upper endof said rod f is connected by a rodf to the rod on, so that said rods f3 and 177, will move in unison, and as said rod on" is attached to theair-receiver b of the air-pressure device and moved by it said rod f andinner tube f, supported by it, will be correspondingly moved up and downwith said air-receiver b.

Contained within and located near the bottom of the tube or cylinder fis a valve f shown as a plug, made considerably smaller in diameter thanthe interior of the tube f and having its lower end formed to seat uponand close the upper end of an inlet-pipe s, which projects up into thelower end of the tube f, passing up through a cap or nut s, which isscrewed onto and closes the lower end of said tubef, and said valve f ismovable toward and from the valve-formed end of said inlet-pipes to openand close the outlet of said pipe. The pipe 3 serves as an inlet-pipefor the admission of hydrocarbon liquid to the tube or cylinderf, andsaid inlet-pipe s is connected by a short pipe with a stand-pipe 0 at .9as hereinafter described and said stand pipe 0 is kept continouslyfilled with the hydrocarbon liquid to a predetermined elevation. Thevalve f is attached to the lower end of a rod f which projects up intothe inner tube or cylinder f, which is contained within the tube orcylinder f, and the upper end of said rod f is bifurcated or 0therwisedivided into several fingers which are sprung apart and caused to engagefrictionally the interior of said inner tube or cylinder f. By thusfrictionally connecting the rod f, to which the valve is attached, withthe short tube or cylinderf", said valve will be raised and lowered bysaid tube or cylinder f A pin 00 is passed through the wall of thecylinder f near its lower end, which projects into the upward path ofmovement of said valve f and said pin 00 serves as a stop to limit theascent of said valve f As the tube f is raised the rod f having thebifurcated end in frictional engagement with the interior thereof, willbe drawn up with it, and the valvef will ascend until it strikes againstthe pin at, and then as the tubef continues to rise the valve f willremain in engagement with the said pin a;, the bifurcated end of the rodf at such time sliding along in said tube. As the tubej descends thevalvef will descend with it until it strikes and is seated upon theupper end of the inlet-pipe 8, closing said inlet, and then owing to thefrictional sliding connection of the rod with said tube f the latter maycontinue to descend for the purpose of expelling the liquid contained ina cylinder f by displacement. Thus the valve f will be lifted andremoved from its seat at the beginning of the ascent of the tubef; butits ascent will be checked by the stop at, and by means of the slidingconnection of the rod with said tube f said tube f may continue toascend, holding the valvef up against said stop, and as the tube'f isconnected with the air-receiver b said tube will rise conj unctivelytherewith, and the result is that the valve remains lifted and openduring the time the air-receiver is rising to store up a supply of air,and during the time that the valve 1" is thus elevated the hydrocarbonliquid is free to enter and rise in the cylinderf to a predeterminedelevation. Thus a quantity of air and a quantity of hydrocarbon liquidare stored up in their respective receivers to be subsequentlydelivered, and it will also be seen that the valve f will be caused todescend and to close upon its seat at the beginning of the descent ofthe tube f to thereby close the inlet, and by means of the aforesaidsliding connection of the rod f with the tube f said tube f will bepermitted to continue its descent con j unctively with the gravitatingair-receiver and,falling in the liquid contained in the cylinder,willact by displacement to expel the liquid, delivering it to the carbureterconjunctively with the delivery of the air.

Leading from the cylinder f of the delivering device, near its upperend, is a small pipe 7L which extends to the carbureter O, and

the hydrocarbon liquid contained in said cylinder f is expelled andcaused to pass through said pipe 7L to the carbureter as the inner tubef descends.

As the tube f is connected with the air-receiver, as before described,it will be seen that it will descend with said air-receiver and willcause the liquid contained in the cylinder f to pass through the pipe Ifat a certain speed proportional to the descent of the airreceiver, sothat the liquid and air will be delivered to the carbureter in uniformproportions and the delivery of the liquid will be absolutely dependentupon the delivery of the air.

It is designed that the hydrocarbon liquid shall rise in the cylinderftoa predetermined height when the inlet-valve is open to thus regulate thequantity to be used proportional to the air which is supplied by theairreceiver, and to accomplish this result we employ a stand-pipe 0which rises from a supply-tank P to asuitable height and which is keptfilled with hydrocarbon liquid to a predetermined height or above acertain level by means to be described, and said stand-pipe 0 is tappedat .9 and the inlet-pipe s is connected to the stand-pipe at such pointand enters the lower end of the cylinder f, as before described, and thepassage through said pipe .9 is controlled by the valve f moving towardand from its inner end, and when said valve is open the hydrocarbonliquid will rise in the cylinder f to a level with the liquid containedin the stand-pipe 0 The outlet h of the cylinder f is just at or abovethe normal level of the hydrocarbon liquid contained in the standpipe 0but the liquid is expelled through said outlet 71 by displacementproduced by the falling tube f when the valve f is closed upon the endof the inlet-pipe s and is conducted to the carbureter C.

To maintain the hydrocarbon liquid at a predetermined height in thestand-pipe 0 we provide a tank 0', (see Figs. 1, 3, and 5,) whichcontains within it a vertical partitionwall 0 dividing it into twocompartments 4 and 5, and said partition-wall 0 terminates just abovethe bottom of said tank to allow free and unobstructed passage beneathit, as at 2. The stand-pipe 0 rising from the supply-tank P, extends ashort distance above the tank 0 and has a T-coupling c at a point abouton a level with said tank, from which a short bent pipe 0 leads to saidtank, opening into the compartment 4 thereof at a point substantiallymidway the height of the tank. NVater is introduced into the tank 0 insuitable quantities, which upon rising therein high enough will entersaid pipe 0 and pass down the stand-pipe 0 into the supply-tank P andupon settling to the bottom of said supply-tank will displace acorresponding quantity of hydrocarbon liquid, which will rise in saidstand-pipe and will enter the compartment 4 of the tank and float uponthe surface of the water therein. The water is introduced into the tank0 by a pipe 0, which is connected with the cylinder b containing thepiston a, and as said piston (1/ falls the water will be conducted intothe compartment 5 of the tank 0' by said pipe 0. It will be seen thatthe cylinder 1) is not vented, and hence the water will be retainedtherein and will only pass out gradually as the piston a falls, althoughit is obvious that the water might be allowed to escape at once and beconducted to the tank 0, and in either case the result will be the same.The water upon entering the compartment 5 of the tank 0' passes beneaththe partition-wall c ,"and thence into and down the stand-pipe 0 but toprovide against the passage of too much water and consequent troublewhich might arise an overflow or waste pipe 6 is provided in thecompartment 5 of the tank 0', the upper end of which terminatessubstantially on a level with the center of the pipe 0 and if more waterenters than is required to raise the hydrocarbon liquid to such apredetermined level in the compartment 4 of the tank 0 then it will becarried away. Thus it will be seen that the hydrocarbon liquid and the.Water establish themselves in the tank a in a ratio corresponding totheir respective specitic gravities. Referring to Fig. 2, the dottedline indicates the level of the water in the compartment 4, above whichis the hydrocarbon liquid, and it will be understood that saidhydrocarbon liquid is maintained at such a predetermined height and thatthe stand-pipe 0 will consequently be filled to such a level, and when aquantity is taken from said stand-pipe to fill the cylinder f of thedelivering device the predetermined level in the tank 0 will necessarilyfall and the Water will rise in said compartment 4 and soon will reachsuch a level as to enter the pipe 0 and to flow down the stand-pipe 0into the supply-tank P and to cause a corresponding quantity ofhydrocarbon liquid to rise. Thus it will be observed that thehydrocarbon liquid is automatically maintained at a predermined heightin order that the delivering device may be refilled as desired.

The carbureter or converter or mixer 0 consists of a tank which containswithin it a coil or worm (P, the upper end of which is connected withthe pipe d and the lower end of which is connected with the pipe W, andsaid reservoir is adapted to be filled with water, which may be warm, ifdesired, to facilitate the evaporation into gas of the hydrocarbonliquid. The hydrocarbon liquid expelled from the cylinder f at 71 passesalong said pipe b and is delivered into the pipe 01 at a point near theconnection of said pipe d with the coil or worm d and then passes downthrough said coil or worm and meets an inflow of air, which enters saidcoil or worm at the bottom through a pipe 61 and the liquid is convertedinto gas by being taken up or commiugled with the air before it reachesthe bottom of the coil, and as a consequence there is no waste.

Anindicating device is preferably provided to ascertain whether or notthe machine is in operation, and, as herein shown, such indicatingdevice consists of two pipes to u, (see Fig. 4,) brought nearly togetherand inclosed within a case it, having a glass front, so that thedropping of the hydrocarbon liquid can be seen. This indicating deviceis connected in the pipe 71 which leads from the delivering device tothe carbureter.

The gas generated in the carbureter passes through the pipes 01 (Z d (Zand (Z to a receiver 92 which may be the rising-and-falling tank of agasometer of any usual orsuitable construction. The passage of the gasalong said pipes to the carbureter is controlled by apressure-regulating valve.

The pressure-regulatin g valve herein shown and which is preferablyemployed consists of a sleeve f, placed within a T- coupling (see Fig.1,) a plunger 3 which fitstightly into the said sleeve 2 and which isconnected to a rod which projects vertically out of the top of theT-coupling, and a lever g pivoted to an upright arm 3 secured to saidrod and resting upon the top of said gas-receiver or gasometer Theheight of the receiving-tank x of the gasometer remains constant whilethe airpressnre device is descending, and the pressure-regulating valveadmits gas to the gasoineter as fast as the gas contained in thegasometer is consumed.

While the cylinder 1) of the air-pressu re device is being lifted thereceiver 00 of the gasometer falls to supply the consumption of gasduring such interval of time; but as soon as the air-pressure device isrefilled and its air-receiver again begins to descend the receiver m ofthe gasometer rises until an equalization of pressure is againestablished.

When the supply tank P becomes filled with water, it will be pumped outin any suitable manner before it is refilled with hydrocarbon liquid.
